Sony Trinitron KV-1393R degaussing?

[AdamAnt316]

Thanks for the replies. What would be the 'proper' procedure for using a soldering gun to demagnetize a CRT? I have a Weller 8200, which hopefully should work for the purpose. Would the aforementioned tape head demagnetizer work as well? I have a Sony which has what looks like a small horseshoe on the end, and an Akai which is smaller.

I assume the 8200 is a gun ? Turn on near front of set, make circles
& pull back making smaller circles as you go. When you see no more
effect turn it off. You can also make a real coil easily.
If that dont do it & you are doing it right........
1) the set was dropped & aperture grill moved = junk
2) something on the neck moved, prob need a manual to
do a set-up, not easy like a delta gun CRT.
If it remagnetizes
1) something is near it
2)degauss not working, rare prob.
Good luck

I have seen on some sony tv's the degauss thermistor will blow one lead off under the board. It usually causes the screen to look terrible.
Pull the circuit board and look around the degauss coil plug for failed solder joints near the plug and that area.
